Fuse Master Premium Kiln Wash and Shelf PrimerHot glass is sticky and it will stick to any hot objects that it touches. Putting Shelf Primer on a mold or kiln shelf is like "greasing the cookie sheet" because it protects them from the glass. Our Shelf Primer is high temperature resistant with minimal sticking and unusually smooth surface, the two exceptional qualities that contribute to a better looking back side, and who doesn't want that?
